For example, observing a dataset and/or an annotation with some distribution of elements may cause the algorithm to create a view containing a sample of the elements with a different distribution. Furthermore, detecting a change of the dataset and/or annotation that caused a change of said distribution may lead the algorithm to modify the view to match the change. Furthermore, when changes to the dataset and/or the annotation cause the said distribution to reach a certain desired property, the algorithm may remove the view.

In this example, method 700 may comprise: obtaining information related to inference models (Step 710); obtaining interrelationships information (Step 720); using the interrelationships information to determine information related to a first inference model (Step 730); and using the determined information related to the first inference model to present the first inference model (Step 740). In some implementations, method 700 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, in some cases Step 710 and/or Step 740 may be excluded from method 700. In some implementations, one or more steps illustrated in FIG. 7 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and/or a plurality of steps may be combined into single step and/or a single step may be broken down to a plurality of steps.

In some embodiments, in Step 710 information related to a group of at least three inference models may be obtained. For example, the information related to the group of at least three inference models may be read from memory (for example from memory unit 210, shared memory module 410, etc.), received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), and so forth. In some examples, information related to a group of at least three inference models obtained by Step 710 may include and/or be based on parameters and/or hyper-parameters of the inference models. In some examples, in Step 710 the information related to the group of at least three inference models may be generated. For example, inference models may be used to generate outputs corresponding to one or more selected inputs, and the generated outputs may be analyzed to determine the information related to the group of at least three inference models. Some examples of such analysis of the generated outputs may include statistical analysis of the outputs, comparison of the generated outputs with desired outputs, and so forth. In another example, information related to the inference model may be analyzed to determine the information related to the group of at least three inference models. For example, each inference model may include an artificial neural network, and properties of the structure of the artificial neural network (such as number of layers, number of artificial neurons in selected layers, type of artificial neurons, activation functions, etc.) may be used to determine the information related to the group of at least three inference models. In some examples, in Step 710 the information related to the group of at least three inference models may be obtained from a single source or from multiple sources. For example, information related to one or more inference models of the group of at least three inference models may be received from a first external device, and information related to one or more other inference models of the group of at least three inference models may be received from a second external device. In another example, information related to one or more inference models of the group of at least three inference models may be received from an external device, and information related to one or more other inference models of the group of at least three inference models may be read from memory. In yet another example, information related to one or more inference models of the group of at least three inference models may be received from an external device and/or read from memory, and information related to one or more other inference models of the group of at least three inference models may be generated as described above.

In some embodiments, in Step 720 a plurality of interrelationship records may be obtained. For example, each interrelationship record may correspond to one subgroup of the group of at least three inference models of Step 710, and in some examples each such subgroup may comprise at least two inference models. Some examples of such subgroups may include subgroups of exactly two inference models, of exactly three inference models, of at least two inference models, of at least three inference models, of at least six inference models, and so forth. For example, one or more interrelationship records may be read from memory (for example from memory unit 210, shared memory module 410, etc.), received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), generated by analyzing the corresponding subgroup of inference models, and so forth. In some examples, one or more interrelationship records may be generated. For example, a machine learning model may be trained using training examples to generate interrelationship records from two or more inference models, and the trained machine learning model may be used to analyze a subgroup of the group of at least three inference models of Step 710 and generate a corresponding interrelationship record. Such training example may include a plurality of inference models together with a desired interrelationship record for the plurality of inference models. In another example, an artificial neural network may be configured to generate interrelationship records from two or more inference models, and the artificial neural network may be used to analyze a subgroup of the group of at least three inference models of Step 710 and generate a corresponding interrelationship record. In yet another example, Step 720 may obtain an interrelationship record corresponding to a subgroup of the group of at least three inference models of Step 710 comprising a measure of similarity (or a measure of dissimilarity) among the inference models of the subgroup. For example, the measure of similarity (or the measure of dissimilarity) may comprise a measure of similarity (or a measure of dissimilarity) among properties of the inference models of the subgroup. In an additional example, Step 720 may obtain an interrelationship record corresponding to a subgroup of the group of at least three inference models of Step 710 comprising a statistical measure (such as mean, median, mode, standard deviation, variance, function of an histogram, and so forth) of a property of the inference models. Some examples of such properties are described throughout this disclosure.

In some examples, in Step 720 structures associated with a plurality of inference models may be compared, for example using an inexact graph matching algorithm, to determine a matching score related to the plurality of inference models. For example, in Step 720 a structure associated with the first inference model and a structure associated with a second inference model may be compared, for example using an inexact graph matching algorithm, to determine a matching score related to the first inference model and the second inference model. Further, in some examples, the determined matching score may be used to determine the information related to the first inference model, for example by Step 730 as described below. For example, each inference model may comprise an artificial neural network, and the network graphs of the artificial neural networks of a plurality of inference models may be compared by Step 720 using an inexact graph matching algorithm to determine a matching score related to the plurality of inference models. In another example, each inference model may comprise an hierarchical model (such as hierarchical clustering model, hierarchical classification model, etc.), and the tree graphs of the hierarchical models of a plurality of inference models may be compared by Step 720 using an inexact tree matching algorithm to determine a matching score related to the plurality of inference models.

In some examples, in Step 720 a first subgroup of the group of at least three inference models may be analyzed to generate the interrelationship record corresponding to the first subgroup, for example as described above. Further, in some examples, the generated interrelationship record corresponding to the first subgroup may be used to determine the information related to the first inference model, for example by Step 730 as described below.

In some embodiments, in Step 730 the plurality of interrelationship records obtained by Step 720 may be used to determine information related to a first inference model of the group of at least three inference models. For example, a machine learning model may be trained using training examples to determine information related to a single inference model from a plurality of interrelationship records, and the trained machine learning model may be used to analyze the plurality of interrelationship records obtained by Step 720 and determine information related to the first inference model. Such training example may include a plurality of interrelationship records, possibly with information about the first inference model, together with desired determined information related to the first inference model. In another example, an artificial neural network may be configured to determine information related to a single inference model from a plurality of interrelationship records, and the artificial neural network may be used to analyze the plurality of interrelationship records obtained by Step 720 and determine information related to the first inference model. In some examples, in Step 730 an interrelationship record corresponding to a subgroup of the group of at least three inference models of Step 710, where the subgroup may comprise exactly two inference models, may be used to determine the information related to the first inference model, for example as described above. In some examples, in Step 730 an interrelationship record corresponding to a subgroup of the group of at least three inference models of Step 710, where the subgroup may comprise at least three inference models (for example, exactly three, exactly four, exactly five, exactly six, more than six, etc.), may be used to determine the information related to the first inference model, for example as described above. In some examples, in Step 730 an interrelationship record corresponding to a subgroup of the group of at least three inference models of Step 710 may comprise a measure of similarity (or a measure of dissimilarity) as described above, and the measure of similarity (or the measure of dissimilarity) may be used to determine the information related to the first inference model. In some examples, in Step 730 an interrelationship record corresponding to a subgroup of the group of at least three inference models of Step 710 may comprise a statistical measure of a property of the inference models as described above, and the statistical measure may be used to determine the information related to the first inference model, for example as described above.

In some examples, in Step 730 interrelationship information based on one or more commonalities among at least two inference models may be used to determine the information related to the first inference model. For example, the at least two inference models may comprise identical parameters and/or hyper-parameters, the values of the parameters and/or hyper-parameters may be compared to find commonalities among the at least two inference models in the form of parameters and/or hyper-parameters with identical or substantially identical values. In another example, each of the at least two inference models may comprise structure, and the structures may be compared to find commonalities among the structures. For example, each of the at least two inference models may comprise an artificial neural network, and the network graphs of the artificial neural networks of the at least two inference models may be compared using an exact graph matching algorithm to find commonalities among the graphs. In another example, each of the at least two inference models may comprise a hierarchical model (such as hierarchical clustering model, hierarchical classification model, etc.), and the tree graphs of the hierarchical models of the at least two inference models may be compared using an exact tree matching algorithm to find commonalities among the trees. Further, in some examples, a measure of similarity among the at least two inference models may be calculated based on the found commonalities among the at least two inference models. For example, number and/or amount and/or size of the commonalities may be used (for example, after normalization, after a comparison with number and/or amount and/or size of distinct features of the at least two inference models, etc.) to determine a measure of similarity of the at least two inference models. Further, in some examples, the measure of similarity of the at least two inference models may be used to determine the information related to the first inference model, for example as described below.

In some examples, in Step 730 interrelationship information related to a measure of similarity among at least two inference models may be used to determine the information related to the first inference model. For example, a machine learning model may be trained using training examples to determine information related to a single inference model from measures of similarities, and the trained machine learning model may be used to analyze at least the measure of similarity among at least two inference models and determine information related to the first inference model. Such training example may include one or more measures of similarities, together with desired determined information related to the first inference model. In another example, an artificial neural network may be configured to determine information related to a single inference model from measures of similarities, and the artificial neural network may be used to analyze at least the measure of similarity among at least two inference models and determine information related to the first inference model.

In some examples, in Step 730 interrelationship information related to a measure based on an interrelationship between a second inference model and a third inference model may be used to determine the information related to the first inference model (for example as described above), wherein both the second inference model and the third inference model may differ from the first inference model.

In some examples, in Step 730 interrelationship information based on a number of layers associated with the first inference model and a number of layers associated with a second inference model may be used to determine the information related to the first inference model. For example, a similarity measure between the first inference model and the second inference model may be calculated based on the number of layers associated with the first inference model and the number of layers associated with the second inference model, and the information related to the first inference model may be determined using the calculated similarity measure as described above. In another example, a statistical measure (such as mean, median, mode, standard deviation, variance, function of an histogram, and so forth) of at least the number of layers associated with the first inference model and the number of layers associated with the second inference model may be calculated, and the information related to the first inference model may be determined using the calculated statistical measure as described above.

In some examples, in Step 730 interrelationship information based on a type of at least one layer of the first inference model and a type of at least one layer of a second inference model may be used to determine the information related to the first inference model. For example, a similarity measure between the first inference model and the second inference model may be determined based on the type of at least one layer of the first inference model and the type of at least one layer of the second inference model (for example using the two types to select an entry in a matrix that holds the determined similarity measure), and the information related to the first inference model may be determined using the determined similarity measure as described above.

In some examples, in Step 730 interrelationship information based on a number of artificial neurons associated with the first inference model and a number of artificial neurons associated with a second inference model may be used to determine the information related to the first inference model. For example, a similarity measure between the first inference model and the second inference model may be calculated based on the number of artificial neurons associated with the first inference model and the number of artificial neurons associated with the second inference model, and the information related to the first inference model may be determined using the calculated similarity measure as described above. In another example, a statistical measure (such as mean, median, mode, standard deviation, variance, function of an histogram, and so forth) of at least the number of artificial neurons associated with the first inference model and the number of artificial neurons associated with the second inference model may be calculated, and the information related to the first inference model may be determined using the calculated statistical measure as described above.

In some examples, in Step 730 interrelationship information based on a type of at least one activation function of the first inference model and a type of at least one activation function of a second inference model may be used to determine the information related to the first inference model. For example, a similarity measure between the first inference model and the second inference model may be determined based on the type of at least one activation function of the first inference model and the type of at least one activation function of the second inference model (for example using the two types to select an entry in a matrix that holds the determined similarity measure), and the information related to the first inference model may be determined using the determined similarity measure as described above.

In some examples, in Step 730 interrelationship information based on a measure of non-linearity associated with the first inference model and a measure of non-linearity associated with a second inference model may be used to determine the information related to the first inference model. For example, an inference model may use a polynomial kernel function, and the measure of non-linearity may be the degree of the polynomial kernel function. In another example, an inference model may use a function, a nonlinearity measure of the function may be sampled at selected points, for example using |tf(x)+(1−t)f(y)−f(tx+(1−t)y)| for some select x, y and t triples, and a function of the sampled nonlinearity measure (such as mean, median, max, min, etc.) may be used as the measure of non-linearity. In one example, a similarity measure between the first inference model and the second inference model may be calculated based on the measure of non-linearity associated with the first inference model and the measure of non-linearity associated with the second inference model, and the information related to the first inference model may be determined using the calculated similarity measure as described above. In another example, a statistical measure (such as mean, median, mode, standard deviation, variance, function of an histogram, and so forth) of at least the measure of non-linearity associated with the first inference model and the measure of non-linearity associated with the second inference model may be calculated, and the information related to the first inference model may be determined using the calculated statistical measure as described above.

In some examples, in Step 730 interrelationship information based on a plurality of results produced using the first inference model and a plurality of results produced using a second inference model may be used to determine the information related to the first inference model. For example, the two pluralities of results may be compared to calculated a similarity measure between the first inference model and the second inference model, and the information related to the first inference model may be determined using the calculated similarity measure as described above. In another example, each plurality of results may be compared with desired results to obtain values related to the results associated with the corresponding inference model (such as numbers and/or ratios of false positives and/or false negatives and/or true positives and/or true negatives, accuracy, precision, F score, confusion matrix, other statistics about classification errors, sum of absolute errors, sum of square errors, other statistics about regression errors, etc.), a statistical measure (such as mean, median, mode, standard deviation, variance, function of an histogram, and so forth) of the values related to the results associated with the first inference model and the values related to the results associated with the second inference model may be calculated, and the information related to the first inference model may be determined using the calculated statistical measure as described above.

In some examples, in Step 730 interrelationship information based on a plurality of confidence levels associated with results produced using the first inference model and a plurality of confidence levels associated with results produced using a second inference model may be used to determine the information related to the first inference model. For example, the two pluralities of confidence levels may be compared to calculated a similarity measure between the first inference model and the second inference model, and the information related to the first inference model may be determined using the calculated similarity measure as described above.

In some examples, in Step 730 the plurality of interrelationship records obtained by Step 720 may be used to determine an embedding of inference models (such as the inference models of Step 710) in a mathematical space (for example in a one dimensional space, in a two dimensional space, in a three dimensional space, in a space with a dimension higher than three, and so forth). For example, an embedding of at least two inference models may be determined, of at least three inference models may be determined, of at least five inference models may be determined, of at least ten inference models may be determined, and so forth. In some examples, a mathematical vector corresponding to an inference model may be obtained, and the mathematical vectors corresponding to the inference models of Step 710 may be used to determine the embedding in the mathematical space of the inference models of Step 710, for example using principal component analysis (PCA), using Fisher's (linear discriminant analysis) LDA, using minor component analysis (MCA), using t-distributed stochastic neighbor embedding (t-SNE), and so forth. For example, an inference model may comprise a matrix, and the mathematical vector corresponding to the inference model may be generated by a mathematical vectorization of the matrix. In another example, an inference model may comprise a number of parameters, and the values of the parameters may be used to construct the mathematical vector corresponding to the inference model. Further, in some examples, the determined embedding of the inference models (in the two dimensional space, in the three dimensional space, and so forth) may be visually presented to a user. For example, determined embedding of the inference models may be presented to the user using a display screen, an augmented reality display system, a printer, and so forth. In another example, the determined embedding of the inference models may be presented to the user using output 800 described below.

In some examples, in Step 730 the plurality of interrelationship records obtained by Step 720 may be used to determine a hierarchical graph of inference models (such as the inference models of Step 710). For example, a hierarchical graph of at least two inference models may be determined, of at least three inference models may be determined, of at least five inference models may be determined, at least ten inference models may be determined, and so forth. For example, the interrelationship records may indicate that a particular inference model is comprise of a composition of one or more other inference models (for example as described below in relation to FIGS. 10C, 10D, 10E, 10F and 10G), and as a result the determined hierarchical graph may have the particular inference model as a parent to the one or more other inference models.

FIGS. 10A, 10B, 100, 10D, 10E, 10F and 10G are schematic illustrations of different configurations for using inference models consistent with embodiments of the present disclosure. In some embodiments, different devices may use different configurations of inference models. In some embodiments, a device may use different configurations of inference models at different times, at different locations, in different contexts, and so forth.

In some embodiments, inference model 1002 may be used to generate output based on provided input, as illustrated in FIG. 10A. In some embodiments additional inference models 1004 may be selected based on the usage of inference model 1002, for example using method 900 as described above. In some embodiments, after a selection of additional inference model 1004, inference model 1002 may be replaced by the selected additional inference model 1004, and the selected additional inference model 1004 may be used to generate output based on provided input, as illustrated in FIG. 10B.

In some embodiments, after a selection of additional inference model 1004, outputs of inference model 1002 may be provided to the selected additional inference model 1004, and the selected additional inference model 1004 may generate output based on the outputs of inference model 1002, as illustrated in FIG. 100. In some examples, inference model 1002 and the selected additional inference model 1004 may be used in a cascade configuration. For example, before providing the outputs of inference model 1002 to the selected additional inference model 1004, the outputs of inference model 1002 may be analyzed to determine whether to provide the outputs of inference model 1002 to the selected additional inference model 1004 or not. Further, in response to a determination not to provide the outputs of inference model 1002 to the selected additional inference model 1004, an output may be generated based on that determination and/or the outputs of inference model 1002, and in in response to a determination to provide the outputs of inference model 1002 to the selected additional inference model 1004, an output may be generated by the selected additional inference model 1004 based on the outputs of inference model 1002.

In some embodiments, after a selection of additional inference model 1004, the selected additional inference model 1004 may be used to generate outputs based on provided inputs, the outputs of the selected additional inference model 1004 may be provided to inference model 1002, and inference model 1002 may generate output based on the outputs of the selected additional inference model 1004, as illustrated in FIG. 10D. In some examples, inference model 1002 and the selected additional inference model 1004 may be used in a cascade configuration. For example, before providing the outputs of the selected additional inference model 1004 to inference model 1002, the outputs of the selected additional inference model 1004 may be analyzed to determine whether to provide the outputs of the selected additional inference model 1004 to inference model 1002 or not. Further, in response to a determination not to provide the outputs of the selected additional inference model 1004 to inference model 1002, an output may be generated based on that determination and/or the outputs of the selected additional inference model 1004, and in in response to a determination to provide the outputs of the selected additional inference model 1004 to inference model 1002, an output may be generated by inference model 1002 based on the outputs of the selected additional inference model 1004.

In some embodiments, after a selection of additional inference model 1004, common inputs may be provided to both inference model 1002 and the selected additional inference model 1004, inference model 1002 may generate a first output (“Output1” in FIG. 10E) based on the provided input, and the selected additional inference model 1004 may generate a second output (“Output2” in FIG. 10E) based on the provided input, as illustrated in FIG. 10E. In some embodiments, after a selection of additional inference model 1004, a first portion of a common input may be provided to inference model 1002 and a second portion of the common input may be provided to the selected additional inference model 1004, inference model 1002 may generate a first output (“Output1” in FIG. 10E) based on the provided first portion of the common input, and the selected additional inference model 1004 may generate a second output (“Output2” in FIG. 10E) based on the provided second portion of the common input, as illustrated in FIG. 10E. For example, the first portion and second portion of the common input may be selected based on the structure of the common input, based on the content of the common input, based on geographical area associated with the common input, based on time associated with the common input, based on context associated with the common input, based on an entity associated with the common input, and so forth. For example, a machine learning algorithm may be trained using training examples to select portions of the common input based on the information listed above, and the trained machine learning algorithm may be used to select the first portion and second portion of the common input based on the information listed above. Some examples of such training examples may include example common inputs and/or example information related to the example common inputs together with a desired selection of portions. In another example, an artificial neural network may be configured to select portions of the common input based on the information listed above, and the artificial neural network may be used to select the first portion and second portion of the common input based on the information listed above.

In some embodiments, after a selection of additional inference model 1004, Component 1006 may determine (for example as described below) whether to provide the input (or selected portions of the input) to inference model 1002, to inference model 1004, to both inference models 1002 and 1004, to none of the two inference models, etc., and in some examples, the inference models that were provided with the input by Component 1006 may generate outputs based on the provided input, for example when an input is provided to inference model 1002 by Component 1006, inference model 1002 may generate a first output (“Output1” in FIG. 10F) based on the provided input, and when an input is provided to the selected additional inference model 1004 by Component 1006, the selected additional inference model 1004 may generate a second output (“Output2” in FIG. 10F) based on the provided input, for example as illustrated in FIG. 10F.

In some embodiments, after a selection of additional inference model 1004, common inputs (or portions of the common inputs selected as described above) may be provided to both inference model 1002 and the selected additional inference model 1004, inference model 1002 may generate a first output (“Output1” in FIG. 10G) based on the provided input, the selected additional inference model 1004 may generate a second output (“Output2” in FIG. 10G) based on the provided input, and the first output (“Output1”) and the second output (“Output2”) may be merged into a unified output by Component 1008 (for example as described below), for example as illustrated in FIG. 10G.

In some embodiments, Component 1006 and/or Component 1008 may be performed by various aspects of apparatus 200, server 300, cloud platform 400, computational node 500, and so forth. For example, processing units 220 may execute software instructions stored within memory units 210 and/or within shared memory modules 410, and the software instructions may be configured to cause processing units 220 to perform the function of Component 1006 and/or Component 1008. In another example, Component 1006 and/or Component 1008 may be implemented by a dedicated hardware. In yet another example, computer readable medium (such as a non-transitory computer readable medium) may store data and/or computer implementable instructions for carrying out the functions of Component 1006 and/or Component 1008.

In some embodiments, Component 1006 may determine to which inference models to provide the input (or selected portions of the input), for example as illustrated in FIG. 10F. In some examples, the determination to which inference models to provide the input (or selected portions of the input) may be based on a type of the input (for example as described above), may be based on a time associated with the input (for example as described above), may be based on a geographical area associated with the input (for example as described above), may be based on a contextual situation associated with the input (for example as described above), may be based on an entity associated with the input (for example as described above), and so forth. In some examples, Component 1006 may analyze the input (or selected parts of the input) to determine to which inference models to provide the input (or selected portions of the input), and/or to select which portions of the input to provide to which inference model. For example, a machine learning algorithm may be trained using training examples to determine which inference models should be provided with which portions of an input based on the content of the input and/or information associated with the input (such as type of the input, time associated with the input, geographical area associated with the input, contextual situation associated with the input, entity associated with the input, etc.), and the trained machine learning algorithm may be used to determine to which portion of the input to provide to which inference models based on the input and/or information associated with the input. For example, such training example may comprise an example of an input and/or of information associated with the example input, together with desired selection of inference models to provide the example input to and/or desired selection of portions of the example input. In another example, an artificial neural network may be configured to determine which inference models should be provided with which portions of an input based on the content of the input and/or information associated with the input (such as type of the input, time associated with the input, geographical area associated with the input, contextual situation associated with the input, entity associated with the input, etc.), and the artificial neural network may be used to determine to which inference models to provide which portions of the input based on the input and/or information associated with the input.

In some embodiments, Component 1008 may merge a plurality of outputs into a unified output, for example as illustrated in FIG. 10G. In some examples, Component 1008 may use a voting mechanism to select one output of the plurality of outputs. For example, such voting mechanism may select the most prevalence output of the plurality of outputs. In some examples, Component 1008 may calculate a statistical measure of the plurality of outputs, and the unified output may be based on the calculated statistical measure. Some examples of such statistical measure may include mean, median, mode, variance, standard deviation, and so forth. In some examples, each output of the plurality of outputs may be associated with a confidence level (for example, with a confidence level produced by the inference model that generated the output, with a confidence level that was calculated for the output, etc.), and Component 1008 may use the confidence levels associated with the outputs to merge the plurality of outputs into a unified output. For example, the output corresponding to the highest confidence level may be selected, a weighted average of the plurality of outputs may be calculated using weights based on the confidence levels, a statistical measure of a subgroup of the plurality of outputs selected based on the confidence levels may be calculated (for example, the subgroup may correspond to outputs associated with the highest confidence levels, to outputs associated with confidence levels higher than a selected threshold, etc.), and so forth.

FIG. 11 illustrates an example of a method 1100 for selective update of inference models. In this example, method 1100 may comprise: obtaining a first inference model and a second inference model based on a first version of a set of training examples (Step 1110); obtaining updated version of the set of training examples (Step 1120); generating updated version of the first inference model based on the updated version of the set of training examples (Step 1130); evaluating the updated version of the first inference model (Step 1140); and determining whether to update the second inference model based on the evaluation result (Step 1150). In some implementations, method 1100 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, in some cases Step 1110 and/or Step 1120 and/or Step 1130 may be excluded from method 1100. In some implementations, one or more steps illustrated in FIG. 11 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and/or a plurality of steps may be combined into single step and/or a single step may be broken down to a plurality of steps.

In some embodiments, in Step 1110 inference models based on a first version of a set of training examples may be obtained. For example, a first inference model and a second inference model may be obtained, where the first inference model and the second inference model may be based on the first version of the set of training examples. For example, the inference models may be a result of training one or more machine learning algorithms using the first version of the set of training examples. In another example, the inference models may be selected of a plurality of alternative inference models based on the first version of the set of training examples. In some examples, the inference models and/or information related to the inference models may be read from memory (for example from memory unit 210, shared memory module 410, etc.), read from a blockchain, received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), generated (for example by training one or more machine learning algorithms using one or more hyper-parameters and/or the first version of the set of training examples), selected (for example as described above), and so forth.

In some embodiments, in Step 1120 an updated version of the set of training examples may be obtained. For example, the first version of the set of training examples of Step 1110 may include at least one example not included in the updated version of the set of training examples obtained by Step 1120. In another example, the updated version of the set of training examples obtained by Step 1120 may include at least one example not included in the first version of the set of training examples of Step 1110. In yet another example, the updated version of the set of training examples obtained by Step 1120 may include at least one modified version of at least one example included in the first version of the set of training examples of Step 1110. In some examples, in Step 1120 update information may be obtained, and in some examples the set of training examples of Step 1110 may be updated according to the obtained update information. For example, the update information may comprise a delta between the first version of the set of training examples and the updated version of the set of training examples, may comprise training examples to be added to the first version of the set of training examples, may comprise indication of training examples to be removed from the first version of the set of training examples, may include indication of training examples to be modified, and so forth. In some examples, in Step 1120 the updated version of the set of training examples may be read from memory (for example from memory unit 210, shared memory module 410, etc.), read from a blockchain, received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), generated (for example as described above), and so forth.

In some embodiments, in Step 1130 an updated version of the first inference model obtained by Step 1110 may be generated based on the updated version of the set of training examples obtained by Step 1120. In some examples, a machine learning algorithm may be trained using the updated version of the set of training examples obtained by Step 1120 to generate the updated version of the first inference model. For example, the machine learning algorithm used to generate the first inference model (for example as described above) may be trained using the updated version of the set of training examples obtained by Step 1120 to generate the updated version of the first inference model. In another example, an additional inference model may be generated and/or obtained based on the updated version of the set of training examples obtained by Step 1120 (for example, in a similar fashion as described above in relation to Step 1110), and the additional inference model may be combined with the first inference model to generate the updated version of the first inference model, for example as described above and illustrated in FIG. 10C and/or FIG. 10D and/or FIG. 10E and/or FIG. 10F and/or FIG. 10G. In some examples, the additional inference model and/or the updated version of the first inference model may be selected of a plurality of alternative inference models based on the updated version of the set of training examples obtained by Step 1120. For example, in response to a first updated version of the set of training examples, one inference model may be selected, and in response to a second updated version of the set of training examples, another inference model may be selected.

In some examples, the first version of the set of training examples of Step 1110 may include at least one example not included in the updated version of the set of training examples obtained by Step 1120, and the at least one example not included in the updated version of the set of training examples may be used by Step 1130 to generate the updated version of the first inference model. For example, in response to a first example included in the first version of the set of training examples and not in the updated version of the set of training examples, Step 1130 may generate a first updated version of the first inference model, and in response to a second example included in the first version of the set of training examples and not in the updated version of the set of training examples, Step 1130 may generate a second updated version of the first inference model different from the first updated version of the first inference model.

In some examples, the updated version of the set of training examples obtained by Step 1120 may include at least one example not included in the first version of the set of training examples of Step 1110, and the at least one example not included in the first version of the set of training examples may be used to generate the updated version of the first inference model. For example, in response to a first example included in the updated version of the set of training examples and not in the first version of the set of training examples, Step 1130 may generate a first updated version of the first inference model, and in response to a second example included in the updated version of the set of training examples and not in the first version of the set of training examples, Step 1130 may generate a second updated version of the first inference model different from the first updated version of the first inference model.

In some embodiments, in Step 1140 the updated version of the first inference model generated by Step 1130 may be evaluated to obtain an evaluation result. In some examples, parameters of the updated version of the first inference model generated by Step 1130 (such as parameters determined by training a machine learning model using hyper-parameters and/or training examples as described above) may be analyzed to evaluate the updated version of the first inference model generated by Step 1130. For example, a statistical measure of the parameters may be calculated, and the statistical measure may be used to evaluate the updated version of the first inference model generated by Step 1130. In another example, a machine learning model may be trained using training examples to generate evaluations of inference models based on parameters of the inference models, and the trained machine learning model may be used to analyze the parameters of the updated version of the first inference model to evaluate the updated version of the first inference model generated by Step 1130. Some examples of such training example may include a set of parameters together with a corresponding desired evaluation. In yet another example, an artificial neural network may be configured to generate evaluations of inference models based on parameters of the inference models, and the artificial neural network may be used to analyze the parameters of the updated version of the first inference model to evaluate the updated version of the first inference model generated by Step 1130. In some examples, the updated version of the first inference model generated by Step 1130 may be evaluated using validation examples and/or test examples to obtain the evaluation result, for example as described above. For example, the updated version of the first inference model generated by Step 1130 may be used to estimate outputs for the example inputs of the validation examples and/or test examples, the estimated outputs may be compared to the corresponding desired outputs, and the evaluation result may be based on the comparison of the estimated outputs and the desired outputs. For example, the evaluation result may be based on a function of one or more of the numbers and/or ratios of false positives and/or false negatives and/or true positives and/or true negatives, accuracy, precision, F score, confusion matrix, other statistics about classification errors, sum of absolute errors, sum of square errors, other statistics about regression errors, and so forth. In some examples, the updated version of the first inference model generated by Step 1130 may be evaluated based on entities and/or tools involved in the generation of the updated version of the first inference model generated by Step 1130. For example, an inference model generated by a first engineer may be evaluated as better than an inference model generated by a second engineer. In another example, an inference model generated using a first tool may be evaluated as better than an inference model generated using a second tool. Some examples of such tools may include hardware (such as computing devices, memory devices, etc.), algorithms (such as machine learning algorithms, data preparation algorithms, etc.), hyper-parameters, and so forth. In some examples, the updated version of the first inference model generated by Step 1130 may be evaluated based on usage of the updated version of the first inference model. For example, the evaluation may be based on amount of usage, time of usage, location of usage, type of usage, and so forth. For example, an inference model that is used more often may be evaluated as better than an inference model that is used less often. In another example, an inference model that is used during selected time intervals may be evaluated as better than an inference model that is used in other time intervals. In yet another example, an inference model that is used at selected locations may be evaluated as better than an inference model that is used at other locations. In an additional example, an inference model that is used in particulate fashion may be evaluated as better than an inference model that is used in a different fashion. In some examples, the updated version of the first inference model generated by Step 1130 may be evaluated based on feedbacks from users. For example, information based on outputs of the updated version of the first inference model generated by Step 1130 may be provided to one or more users, the one or more users may provide feedbacks relating to the provided information, and the updated version of the first inference model generated by Step 1130 may be evaluated based on those feedbacks.

In some embodiments, in Step 1150 the evaluation result obtained by Step 1140 may be used to determine whether to update the second inference model obtained by Step 1110. For example, in response to a first evaluation result (for example, a positive evaluation result, an evaluation result above a selected threshold, an evaluation result within a selected range, etc.), it may be determined to update the second inference model obtained by Step 1110, and in response to a second evaluation result (for example, a negative evaluation result, an evaluation result below a selected threshold, an evaluation result within a selected range, etc.), it may be determined not to update the second inference model obtained by Step 1110.

In some embodiments, the update to the second inference model obtained by Step 1110 may be based on the evaluation result obtained by Step 1140. For example, in response to a first evaluation result (for example, a positive evaluation result, an evaluation result above a selected threshold, an evaluation result within a selected range, etc.), a first update to the second inference model obtained by Step 1110 may be selected, and in response to a second evaluation result (for example, a negative evaluation result, an evaluation result below a selected threshold, an evaluation result within a selected range, etc.), a second update to the second inference model obtained by Step 1110 may be selected.

In some examples, the first inference model obtained by Step 1110 may be a result of training a machine learning algorithm using a first training set (for example as described above), the second inference model obtained by Step 1110 may be a result of training the same or a different machine learning algorithm using a second training set (for example as described above), and both the first training set and the second training set may comprise the set of training examples of Step 1110. For example, the second training set may differ from the first training set. In another example, the second training set may be identical to the first training set.

In some examples, the first inference model obtained by Step 1110 may be a result of training a first machine learning algorithm using the set of training examples of Step 1110 (for example as described above), the second inference model obtained by Step 1110 may be a result of training a second machine learning algorithm using the set of training examples of Step 1110 (for example as described above), the updated version of the first inference model generated by Step 1130 may be a result of training the first machine learning algorithm using the updated version of the set of training examples obtained by Step 1120 (for example as described above), and updating the second inference model may comprise training the second machine learning algorithm using the updated version of the set of training examples obtained by Step 1120 (for example as described above).

In some examples, the first inference model obtained by Step 1110 may be a result of training a machine learning algorithm using the set of training examples of Step 1110 and a first hyper-parameter of the machine learning algorithm (for example as described above), the second inference model obtained by Step 1110 may be a result of training the machine learning algorithm using the set of training examples of Step 1110 and a second hyper-parameter of the machine learning algorithm (for example as described above), the updated version of the first inference model generated by Step 1130 may be a result of training the machine learning algorithm using the updated version of the set of training examples obtained by Step 1120 and the first hyper-parameter of the machine learning algorithm (for example as described above), and updating the second inference model may comprise training the machine learning algorithm using the updated version of the set of training examples obtained by Step 1120 and the second hyper-parameter of the machine learning algorithm (for example as described above).

In some examples, the first inference model obtained by Step 1110 may be used by a first personalized device, and the second inference model obtained by Step 1110 may be used by a second personalized device. Further, in some examples, in response to a first evaluation result (for example, a positive evaluation result, an evaluation result above a selected threshold, an evaluation result within a selected range, etc.), the second personalized device may be caused to use an updated version of the second inference model (for example as described below), and in response to a second evaluation result (for example, a negative evaluation result, an evaluation result below a selected threshold, an evaluation result within a selected range, etc.), causing the second personalized device to use the updated version of the second inference model may be withheld and/or forwent.

In some examples, the first inference model obtained by Step 1110 may be used by a first personalized device, the second inference model obtained by Step 1110 may be used by a second personalized device. Further, in some examples, the first personalized device may be caused to use the updated version of the first inference model generated by Step 1130 (for example as described below). Further, in some examples, results of the usage of the updated version of the first inference model by the first personalized device may be received (for example from the first personalized device, from a third device, through a communication network using a communication device, through digital memory, and so forth). Further, in some examples, in Step 1140 the received results of the usage of the updated version of the first inference model by the first personalized device may be used to evaluate the updated version of the first inference model and obtain the evaluation result, for example as described above.

In some examples, the first inference model and the second inference model obtained by Step 1110 may be used by a first personalized device.

In some embodiments, in Step 1330 the results obtained by Step 1320 and/or the corresponding groups of values of hyper parameters obtained by Step 1310 may be used to select at least one value of a hyper parameter for a prospective training of a machine learning algorithm (for example, for a prospective training of the machine learning algorithm of Step 1320, for a prospective training of a different machine learning algorithm, and so forth).

For example, a machine learning model may be trained using training examples to select hyper parameters for prospective trainings of machine learning algorithms based on results of training machine learning algorithms and corresponding groups of values of hyper parameters, and the trained machine learning algorithm may be used to analyze the results obtained by Step 1320 and the corresponding groups of values of hyper parameters obtained by Step 1310 to select the at least one value of the hyper parameter for the prospective training of a machine learning algorithm. Such training example may include a plurality of results of training machine learning algorithms with the corresponding groups of values of hyper parameters, together with a desired selection of at least one value of the hyper parameter for the prospective training of the machine learning algorithm. In another example, an artificial neural network may be configured to select hyper parameters for prospective trainings of machine learning algorithms based on results of training machine learning algorithms and corresponding groups of values of hyper parameters, and the artificial neural network may be used to analyze the results obtained by Step 1320 and the corresponding groups of values of hyper parameters obtained by Step 1310 to select the at least one value of the hyper parameter for the prospective training of a machine learning algorithm. In yet another example, a weight may be assigned to groups of values of hyper parameters obtained by Step 1310 according to results obtained by Step 1320, a weighted average of the values of hyper parameters may be calculated using the assigned weights, and the selection of the at least one value of the hyper parameter for the prospective training of a machine learning algorithm may be based on the calculated weighted average. In an additional example, a weight may be assigned to groups of values of hyper parameters obtained by Step 1310 according to results obtained by Step 1320, weighted voting among the values of hyper parameters may be calculated using the assigned weights, and the at least one value of the hyper parameter for the prospective training of a machine learning algorithm may be selected to be similar or identical to the values of hyper parameters selected through voting. For example, the higher weights may be assigned to values of hyper parameters corresponding to better results, higher weights may be assigned to values of hyper parameters corresponding to lesser results, and so forth.

For example, the embedded value with the maximal distance to the nearest other embedded value may be select. In another example, the embedded value with the minimal average distance to the k nearest other embedded values may be selected.

In some examples, it may be determined whether the first result is preferable to the second result and the third result.

Further, in some examples, one or more feedbacks related to the information based on the first plurality of outputs may be received from the at least one user. Further, in some examples, the one or more feedbacks related to the information based on the first plurality of outputs may be used to determine the first result. Some examples of possible implementations of a user interface for providing information based on at least one output to a user and receiving feedbacks related to the information are provided in FIGS. 14A and 14B as described below, and the such user interface may be used repeatedly to obtain feedbacks related to information based on the first plurality of outputs.

In some embodiments, in Step 1510 an indication of a selected object type of a plurality of alternative object types may be received. Some non-limiting examples of such object types may include object together with adjunct related objects, object without adjunct related objects, object together with occluded parts, object without occluded parts, single instance of an object of a specified type, one or more instances of objects of a specified type, person, person together with objects held by the person, person not including objects held by the person, person including occluded parts, person except for occluded parts, male, female, face, face including occluded parts, face excluding occluded parts, face including hair, face excluding hair, vehicle, specific types of vehicles (such as motorcycles, cars, trucks, bicycles, etc.), vehicle with occluded parts, vehicle without occluded parts, motorcycles including their rider, motorcycles not including their riders, and so forth. In some examples, the plurality of alternative object types may be presented to the user, and in Step 1510 the indication of the selected object type of the plurality of alternative object types may be received from the user. In some examples, the image may be analyzed to select the selected object type of the plurality of alternative object types. For example, a machine learning model may be trained using training examples to select object types based on images and/or videos, and the trained machine learning model may be used to analyze the image and select the selected object type. Some examples of such training example may include an image together with the desired selection of the object type. In another example, an artificial neural network may be configured to select object types based on images and/or videos, and the artificial neural network may be used to analyze the image and select the selected object type. In some examples, the selected object type may be selected of the plurality of alternative object types at random. In some examples, the selected object type may be received from the user using a user interface (for example, using a keyboard, using a computer mouse, using a touch screen, using gestures, etc.), read from memory (for example from memory unit 210, shared memory module 410, etc.), read from a blockchain, received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), and so forth.

In some embodiments, in Step 1520 an image may be presented to a user. For example, an image may be presented to a user using a display screen, an augmented reality display system, a printer, and so forth. For example, the image may comprise a depiction of one or more items.

In some embodiments, in Step 1530 an input to an object selection tool may be received, for example from the user. For example, the input to the object selection tool may be received from the user using a user interface (for example, using a keyboard, using a computer mouse, using a touch screen, using gestures, etc.), read from memory (for example from memory unit 210, shared memory module 410, etc.), read from a blockchain, received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), and so forth. Some non-limiting examples of such inputs to the object selection tool may include an indication of one or more positions within the image presented by Step 1520, an indication of one or more regions within the image presented by Step 1520, an indication of one or more contours within the image presented by Step 1520, an indication of one or more masks of the image presented by Step 1520, an indication of one or more subsets of the pixels of the image presented by Step 1520, and so forth.

In some embodiments, in Step 1540, a region of the image corresponding to an object of the selected object type of Step 1510 in the image presented by Step 1520 may be selected based on the input to the object selection tool received by Step 1530 and the selected object type of Step 1510. In some examples, in response to a first selected object type and the input to the object selection tool, a first region of the image corresponding to an object of the first selected object type in the image may be selected, and in response to a second selected object type and the input to the object selection tool, a second region of the image corresponding to an object of the second selected object type in the image may be selected, where the first region may differ from the second region. For example, a machine learning model may be trained using training examples to select regions of images according to inputs to object selection tools and object types, and the trained machine learning model may be used to analyze the image and select the region based on the input to the object selection tool received by Step 1530 and the selected object type of Step 1510. An example of such training example may include an image with an input to an object selection tool and a selection of object type, together with the desired selection of a region in the image. In another example, an artificial neural network may be configured to select regions of images according to inputs to object selection tools and selection of object types, and the artificial neural network may be used to analyze the image and select the region based on the input to the object selection tool received by Step 1530 and the selected object type of Step 1510. In yet another example, a plurality of alternative object selection tools may be available, where each one or the alternative object selection tools may correspond to a particular object type, an object selection tool corresponding to the selected object type of Step 1510 may be selected of the plurality of alternative object selection tools, the input to the object selection tool received by Step 1530 may be provided to the selected object selection tool corresponding to the selected object type of Step 1510, and selection of the region of the image by Step 1540 may be based on the output of the selected object selection tool corresponding to the selected object type of Step 1510.

For example, the first selected object type of Step 1510 may be a person together objects held by the person and the second selected object type of Step 1510 may be a person not including objects held by the person, in response to the first selected object type and the input to the object selection tool received by Step 1530, a first region of the image corresponding to a person and an object held by the person in the image may be selected by Step 1540, and in response to the second selected object type and the input to the object selection tool received by Step 1530, a second region of the image corresponding to the person without the object held by the person in the image may be selected by Step 1540, and therefore the first region may differ from the second region. Some examples of objects held by the person may include bags, cap, smartphone, jacket, and so forth. For example, Step 1520 may present an image of a person holding a bag in a room, and Step 1530 may receive a bounding box around the person holding the bag, as illustrated in FIG. 16A. Further, in this example, in response to an indication of a selected object type of a person together objects held by the person received by Step 1510 and the bounding box received by Step 1530, a region of the image corresponding to the person and the bag held by the person in the image may be selected by Step 1540 as illustrated in FIG. 16B. Further, in this example, in response to an indication of a selected object type of a person not including objects held by the person received by Step 1510 and the bounding box received by Step 1530, a region of the image corresponding to the person without the bag held by the person in the image may be selected by Step 1540 as illustrated in FIG. 16C.

In another example, the first selected object type of Step 1510 may be a person including occluded parts and the second selected object type of Step 1510 may be a person except for occluded parts. in response to the first selected object type and the input to the object selection tool received by Step 1530, a first region of the image corresponding to a person together with parts of the person that are occluded in the image may be selected by Step 1540, and in response to the second selected object type and the input to the object selection tool received by Step 1530, a second region of the image corresponding to the person without the parts of the person that are occluded in the image may be selected by Step 1540, and therefore the first region may differ from the second region. In some examples, a machine learning model may be trained using training examples to estimate the region of the image corresponding to the person including to parts of the person that are occluded in the image based on the visible parts of the person in the image and/or other visual data in the image, and the trained machine learning model may be used to analyze the image and select the region of the image frame corresponding to the person together with parts of the person that are occluded in the image. An example of such training example may include an image together with the desired selection of a region in the image. In some examples, the image may be an image frame from a video, and parts of the person that are occluded in the image frame may be visible in other frames of the video (for example, in consecutive frames, in a different segment of the video, and so forth). Further, in one example, a machine learning model may be trained using training examples to estimate the region of the image frame corresponding to the person (including parts of the person that are occluded in the image frame) based on other frames of the video, and the trained machine learning model may be used to analyze the video and select the region of the image frame corresponding to the person together with parts of the person that are occluded in the image. An example of such training example may include a video together with a desired selection of a region in an image frame of the video corresponding to a person including parts of the person that are occluded in that image frame. For example, Step 1520 may present an image of a person behind a fruit stand, and Step 1530 may receive an indication of the person (for example by an “x” marker pointing to the depiction of the person in the image), as illustrated in FIG. 16D. Further, in this example, in response to an indication of a selected object type of a person including occluded parts received by Step 1510 and the input “x” marker received by Step 1530, a region of the image corresponding to the person including occluded parts of the person may be selected by Step 1540 as illustrated in FIG. 16D. Further, in this example, in response to an indication of a selected object type of a person except for occluded parts of the person received by Step 1510 and the input “x” marker received by Step 1530, a region of the image corresponding to the person without the occluded parts of the person may be selected by Step 1540 as illustrated in FIG. 16F.

In yet another example, the first selected object type of Step 1510 may be male and the second selected object type of Step 1510 may be female, in response to the first selected object type and the input to the object selection tool received by Step 1530, a first region of the image corresponding to a male figure in the image may be selected by Step 1540, and in response to the second selected object type and the input to the object selection tool received by Step 1530, a second region of the image corresponding to a female figure in the image may be selected by Step 1540, and therefore the first region may differ from the second region.

In an additional example, the first selected object type of Step 1510 may be face including hair and the second selected object type of Step 1510 may be face except for hair, in response to the first selected object type and the input to the object selection tool received by Step 1530, a first region of the image corresponding to a face and the hair corresponding to the face in the image may be selected by Step 1540, and in response to the second selected object type and the input to the object selection tool received by Step 1530, a second region of the image corresponding to the face except for the hair corresponding to the face in the image may be selected by Step 1540, and therefore the first region may differ from the second region.

In yet another example, the first selected object type of Step 1510 may be a single instance of an object of a specified object type and the second selected object type of Step 1510 may be one or more instances of objects of the specified object type, in response to the first selected object type and the input to the object selection tool received by Step 1530, a first region of the image corresponding to a single instance of an object in the image may be selected by Step 1540, and in response to the second selected object type and the input to the object selection tool received by Step 1530, a second region of the image corresponding to a plurality of instances of the object in the image may be selected by Step 1540, and therefore the first region may differ from the second region.

In an additional example, the first selected object type of Step 1510 may be a person and the second selected object type of Step 1510 may be a vehicle, in response to the first selected object type and the input to the object selection tool received by Step 1530, a first region of the image corresponding to a person in the image may be selected by Step 1540, and in response to the second selected object type and the input to the object selection tool received by Step 1530, a second region of the image corresponding to a vehicle in the image may be selected by Step 1540, and therefore the first region may differ from the second region.

In yet another example, the first selected object type of Step 1510 may be a car and the second selected object type of Step 1510 may be a truck, in response to the first selected object type and the input to the object selection tool received by Step 1530, a first region of the image corresponding to a car in the image may be selected by Step 1540, and in response to the second selected object type and the input to the object selection tool received by Step 1530, a second region of the image corresponding to a truck in the image may be selected by Step 1540, and therefore the first region may differ from the second region.

In some examples, the input to the object selection tool received by Step 1530 may comprise one or more points in the image (for example the input may indicate that the one or more points are part of the object), and the region of the image selected by Step 1540 may include the one or more points and at least one additional pixel of the image. Further, in some examples, the input to the object selection tool received by Step 1530 may comprise one or more additional points in the image (for example the input may indicate that the one or more additional points are not part of the object), and the region of the image selected by Step 1540 may not include any of the one or more additional points. For example, selecting the region of the image selected by Step 1540 may comprise solving an optimization problem that optimize some criterion function over the selected region under some constraints about the valid selected regions, and in some examples the constraints may specify that the one or more points must be within the selected region and/or that the one or more additional points must be outside the selected region.

In some examples, the input to the object selection tool received by Step 1530 may comprise one or more scribbles in the image (for example the input may indicate that the one or more areas indicated by the scribbles are part of the object), and the region of the image selected by Step 1540 may include the one or more scribbles and at least one additional pixel of the image. Further, in some examples, the input to the object selection tool received by Step 1530 may comprise one or more additional scribbles in the image (for example the input may indicate that the one or more areas indicated by the additional scribbles are not part of the object), and the region of the image selected by Step 1540 may not include any of the one or more additional scribbles. For example, selecting the region of the image selected by Step 1540 may comprise solving an optimization problem that optimize some criterion function over the selected region under some constraints about the valid selected regions, and in some examples the constraints may specify that the one or more areas indicated by the scribbles must be within the selected region and/or that the one or more areas indicated by the additional scribbles must be outside the selected region.

In some examples, the input to the object selection tool received by Step 1530 may comprise a bounding polygon (such as a bounding box, a bounding triangle, etc.), and the region of the image selected by Step 1540 may be included within the bounding polygon. For example, selecting the region of the image selected by Step 1540 may comprise solving an optimization problem that optimizes some criterion function over the selected region under some constraints about the valid selected regions, and in some examples the constraints may specify that the selected region must be contained within the bounding polygon.

In some embodiments, after the selection of the first region of the image corresponding to the object of the first selected object type in the image by Step 1540, an indication of a desire to change the selected object type to an updated object type may be received from the user (where the updated object type differs from the first selected object type), and in response to the received indication of the desire to change the selected object type, the updated object type and the input to the object selection tool may be used to select a modified region of the image corresponding to an object of the updated object type in the image. For example, Step 1540 may be repeated with the updated object type and the input to the object selection tool to select the modified region of the image corresponding to the object of the updated object type in the image.

In some examples, an overlay may be presented over the presentation of the image, and the overlay may indicate the region of the image selected by Step 1540. For example, the overlay may include a bounding contour of the selected region. In another example, the selected region may be presented with a first color scheme while the rest of the image may be presented with a second color scheme. In yet another example, the selected region may be presented with a first blurring settings (for example, without blurring, with low blurring, etc.) while the rest of the image may be presented with a second blurring settings. In an additional example, an overlay may include a first pattern over the selected region (for example, no pattern, dots pattern, lines pattern, and so forth) and a different pattern over the rest of the image (for example, no pattern, dots pattern, lines pattern, and so forth).

In some examples, a dataset of images and masks (for example of datasets 610) may be updated according to the region of the image selected by Step 1540. For example, the image presented by Step 1520 and a mask corresponding to the region of the image selected by Step 1540 may be added to the dataset. In another example, the image presented by Step 1520 may already be part of the dataset, and a mask corresponding to the region of the image selected by Step 1540 may be added to the dataset in connection to the image and/or may replace another mask in the dataset that is connected with the image.

In some embodiments, the image presented by Step 1520 and the input to the object selection tool received by Step 1530 may be analyzed to determine whether a region of the image corresponding to the input to the object selection tool depicts an object of the selected object type of Step 1510. Further, in some examples, in response to a determination that the region of the image corresponding to the input to the object selection tool does not depict an object of the selected object type, an indication may be provided to the user. For example, the indication may be provided visually, may be provided audibly, may be provided textually, may be provided through a personalized device associated with a user, may be provided through a public device, and so forth. In some examples, a machine learning model may be trained using training examples to determine whether regions of images indicated by inputs to object selection tools depict objects of particular types, and the trained machine learning model may be used to analyze the image presented by Step 1520 and the input to the object selection tool received by Step 1530 to determine whether the region of the image corresponding to the input to the object selection tool depicts an object of the selected object type of Step 1510. An example of such training example may include an image and an input to the object selection tool together with an indication of whether the region of the image corresponding to the input to the object selection tool depicts an object of a selected object type. In another example, an artificial neural network may be configured to determine whether regions of images indicated by inputs to object selection tools depict objects of particular types, and the artificial neural network may be used to analyze the image presented by Step 1520 and the input to the object selection tool received by Step 1530 to determine whether the region of the image corresponding to the input to the object selection tool depicts an object of the selected object type of Step 1510.

FIG. 17 illustrates an example of a method 1700 for selecting images for manual annotation. In this example, method 1700 may comprise: accessing at least four images (Step 1710); presenting at least two images of the at least four images (Step 1720); receiving annotation data for the presented at least two images (Step 1730); analyzing the received annotation data (Step 1740); selecting additional images of the at least four images (Step 1750); presenting the selected additional images (Step 1760); and receiving annotation data for the selected additional images (Step 1770). In some implementations, method 1700 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, in some cases Step 1710 and/or Step 1720 and/or Step 1750 and/or Step 1760 may be excluded from method 1700. In some implementations, one or more steps illustrated in FIG. 17 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and/or a plurality of steps may be combined into single step and/or a single step may be broken down to a plurality of steps.

In some embodiments, in Step 1710 a group of images may be accessed. Further, in some examples, points in time corresponding to the group of images may also be accessed. For example, the group of images may comprise a first image that may correspond to a first point in time, a second image that may correspond to a second point in time and at least two more images, each image of the at least two more images may correspond to a point in time. For example, an image may correspond to a time of capturing of the image, may correspond to a time of processing of the image, may correspond to a time associated with an object depicted in the images (for example, a sample may be depicted in the image and the image may correspond to the sampling time of the sample, a document may be depicted in the image and the image may correspond to editing time of the document, etc.), and so forth. In another example, the images may be frames in video, and the images may correspond to time indices of the frames within the video. For example, in Step 1710, the group of images and/or the points in time corresponding to the group of images may be read from memory (for example from memory unit 210, shared memory module 410, etc.), read from a blockchain, received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), and so forth. In another example, in Step 1710 the group of images may be captured using image sensors (such as image sensor 260), may be extracted from a video, and so forth. In yet another example, in Step 1710 metadata associated with the images (such as file name, time associated with the image as described above, description of the image, and so forth) may be accessed.

In some embodiments, in Step 1720 at least part of at least some of the images of the group of images accessed by Step 1710 may be presented to a user. For example, at least part of the first image of the group of images obtained by Step 1710 and/or at least part of the second image of the group of images accessed by Step 1710 may be presented to the user. For example, (the parts of) the images may be presented through a user interface, through a web service, through a display screen, through an augmented reality system, through a personalized device of the user, through a public device, through an external device, and so forth.

In some embodiments, in Step 1730 annotation data associated with the images of the group of images accessed by Step 1710 and/or presented by Step 1720 may be received from the user. For example, first annotation data associated with the first image of the group of images obtained by Step 1710 and/or second annotation data associated with the second image of the group of images obtained by Step 1710 may be received from the user. For example, in Step 1730 the annotation data may be read from memory (for example from memory unit 210, shared memory module 410, etc.), read from a blockchain, received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), and so forth. For example, the annotation data of Step 1730 and/or the annotation data of Step 1770 may comprise a label of an image and/or of an item depicted in the image, a tag of an image and/or of an item depicted in the image, a classification of the image and/or of an item depicted in the image, an indication of a location of an object within the image (for example as a point, a mask, a bounding polygon, and so forth), a value associated with the image and/or of an item depicted in the image, a textual description of the image and/or of an item depicted in the image, a segmentation of the image, and so forth.

In some embodiments, in Step 1740 the annotation data received by Step 1730 and associated with the images of the group of images accessed by Step 1710 and/or presented by Step 1720 may be analyzed. In some examples, in Step 1740 the first annotation data and the second annotation data received by Step 1730 may be compared. For example, a label of the first annotation data may be compared with a label of the second annotation data to determine whether the two are identical or not and/or to calculate a measure of similarity between the two, a tag of the first annotation data may be compared with a tag of the second annotation data to determine whether the two are identical or not and/or to calculate a measure of similarity between the two, a classification data of the first annotation data may be compared with a classification data of the second annotation data to determine whether the two are identical or not and/or to calculate a measure of similarity between the two, a value of the first annotation data may be compared with a value of the second annotation data to determine whether the two are identical or not and/or to calculate a measure of similarity between the two, a location within a first image of the first annotation data may be compared with a location within a second image of the second annotation data to determine whether the two are identical or not and/or to calculate a measure of similarity between the two, a region of a first image of the first annotation data may be compared with a region of a second image of the second annotation data to determine whether the two are identical or not and/or to calculate a measure of similarity between the two, textual information of the first annotation data may be compared with textual information of the second annotation data to determine whether the two are identical or not and/or to calculate a measure of similarity between the two, and so forth. For example, a similarity between two values may be calculated as a monotonically decreasing function of a distance between the two values, as a function of a correlation between the two values, and so forth. In another example, a similarity between two regions may be calculated using the Jaccard index of the two regions, using the Sørensen-Dice coefficient of the two regions, using the Tversky index of the two regions, and so forth. In yet another example, a similarity between two texts may be calculated using a most-frequent-k-characters distance, hamming distance, distance between the two texts in an embedded space (for example, embedded space created using word2vec algorithm), and so forth.

In some embodiments, in Step 1750 additional images may be selected of the group of images accessed by Step 1710. For example, a third image may be selected of the at least two more images accessed by Step 1710. For example, the additional images (such as the third image above) may be selected based on, for example, a result of the analysis of Step 1740 (for example, based on a result of the comparison of the first annotation data and the second annotation data by Step 1740), and the points in time corresponding to the group of images accessed by Step 1710 (for example, the first point in time, the second point in time, and the points in time corresponding to at least some of the at least two more images). For example, a machine learning model may be trained using training examples to select images of a plurality of alternative images based on comparison results and/or points in time, and the trained machine learning model may be used to analyze the comparison of the first annotation data and the second annotation data by Step 1740 and/or and the points in time corresponding to the group of images accessed by Step 1710 and select the additional images of the at least two more images accessed by Step 1710. An example of such training example may comprise comparison results and/or points in time, together with a desired selection of images of a plurality of alternative images. In another example, an artificial neural network may be configured to select images of a plurality of alternative images based on comparison results and/or points in time, and the artificial neural network may be used to analyze the comparison of the first annotation data and the second annotation data by Step 1740 and/or and the points in time corresponding to the group of images accessed by Step 1710 and select the additional images of the at least two more images accessed by Step 1710. In yet another example, the selection of the additional images of the at least two more images accessed by Step 1710 by Step 1750 may be based on one or more of a comparison of a label of the first annotation data with a label of the second annotation data as described above, a comparison of a tag of the first annotation data with a tag of the second annotation data as described above, a comparison of a classification data of the first annotation data with a classification data of the second annotation data as described above, a comparison of a value of the first annotation data with a value of the second annotation data as described above, a comparison of a location within a first image of the first annotation data with a location within a second image of the second annotation data as described above, a comparison of a region within a first image of the first annotation data with a region within a second image of the second annotation data as described above (for example based on one or more of the Jaccard index of the two regions, the Sørensen-Dice coefficient of the two regions, the Tversky index of the two regions, etc.), a comparison of textual information of the first annotation data with textual information of the second annotation data as described above, and so forth.

In some examples, in Step 1750, in response to a first result of the analysis of Step 1740 (for example, in response to a first result of the comparison of the first annotation data and the second annotation data by Step 1740), the third image of the at least two more images may be selected such that the third image corresponds to a point in time between the first point in time and the second point in time, and in response to a second result of the analysis of Step 1740 (for example, in response to a second result of the comparison of the first annotation data and the second annotation data), the third image of the at least two more images corresponding to a third point in time may be selected such that the second point in time is between the first point in time and the third point in time.

In some examples, in Step 1750, in response to a first result of the analysis of Step 1740 (for example, in response to a first result of the comparison of the first annotation data and the second annotation data by Step 1740), the third image of the at least two more images may be selected such that the third image corresponds to a point in time closer to the first point in time than to the second point in time, and in response to a second result of the analysis of Step 1740 (for example, in response to a second result of the comparison of the first annotation data and the second annotation data), the third image of the at least two more images may be selected such that the third image corresponds to a point in time closer to the second point in time than to the first point in time.

In some embodiments, in Step 1760 at least part of the additional images selected by Step 1750 may be presented to the user. For example, in Step 1760 at least part of the third image selected by Step 1750 may be presented to the user. For example, at least part of the additional images selected by Step 1750 may be presented to the user. For example, (the parts of) the additional images may be presented through a user interface, through a web service, through a display screen, through an augmented reality system, through a personalized device of the user, through a public device, through an external device, and so forth.

In some embodiments, in Step 1770 annotation data associated with the additional images selected by Step 1750 and/or presented by Step 1760 may be received from the user. For example, third annotation data associated with the third image selected by Step 1750 and/or presented by Step 1760 may be received from the user. For example, in Step 1770 the annotation data may be read from memory (for example from memory unit 210, shared memory module 410, etc.), read from a blockchain, received through a communication network (such as communication network 130) using a communication device (such as communication module 230), received from an external device (such as mobile phone 111, tablet 112, PC 113, remote storage 140, NAS 150, server 300, cloud platform 400, etc.), and so forth.

In some examples, a dataset of images and annotations (for example of datasets 610) may be updated according to the additional images selected by Step 1750 and/or presented by Step 1760 (such as the selected third image) and the annotation data associated with the additional images and received from the user by Step 1770 (such as the third annotation data received from the user by Step 1770). For example, the image and the annotation data may be added to the dataset. In another example, the image may already be part of the dataset, and the annotation data may be added to the dataset in connection to the image and/or may replace another annotation data in the dataset that is connected with the image.

In some embodiments, a quantity may be selected based on a result of the analysis of Step 1740 (for example, based on a result of the comparison of the first annotation data and the second annotation data by Step 1740), for example as described below. Further, in some examples, in Step 1750 a set of images may be selected of the at least two more images accessed by Step 1710, such that a quantity of images in the selected set of images matches the selected quantity, for example as described below. Further, in some examples, the selected set of images may be presented to the user, for example as described above in relation to Step 1720. Further, in some examples, annotation data associated with each of the selected set of images may be received from the user, for example as described above in relation to Step 1730.

In some examples, a quantity may be selected based on a result of the analysis of Step 1740 (for example, based on a result of the comparison of the first annotation data and the second annotation data by Step 1740). For example, in response to a first result of the analysis of Step 1740 (for example, a first result of the comparison of the first annotation data and the second annotation data by Step 1740), a first quantity may be selected, and in response to a second result of the analysis of Step 1740 (for example, a second result of the comparison of the first annotation data and the second annotation data by Step 1740), a second quantity may be selected. In another example, the quantity may be a function of the result of the analysis of Step 1740 (for example, a function of a result of the comparison of the first annotation data and the second annotation data by Step 1740). In yet another example, a machine learning model may be trained to select quantities based on comparison results, and the trained machine learning model may be used to analyze the comparison result of Step 1740 and select the quantity.

In some examples, in Step 1750 a set of images may be selected of the at least two more images accessed by Step 1710, such that a quantity of images in the selected set of images matches the selected quantity. For example, the selection of the set of images may be performed by Step 1750 as described above. In another example, Step 1750 may select a quantity of images that is higher than the desired quantity, the images may be ranked, and the images with the highest rank may be picked such that the quantity of picked images matches the selected quantity. For example, Step 1750 may use a machine learning model as described above, many machine learning models may further produce a confidence level for each selected image, and such confidence levels may be used for ranking the images (having a higher rank for an image corresponding to a higher confidence). In yet another example, the selected (parts of) images may be ranked according to size, assigning a higher rank for larger images.

In some embodiments, an embedding in a mathematical space of the group of images accessed by Step 1710 may be determined, for example as described below. Further, in some examples, in Step 1750 the determined embedding of the images in the mathematical space may be used to select additional images of the group of images accessed by Step 1710, for example as described below.

In some examples, an embedding in a mathematical space of the group of images accessed by Step 1710 may be determined. For example, an embedding in a mathematical space of at least the first image, the second image and the at least two more images accessed by Step 1710 may be determined, for example as described below.

In some examples, the embedding in the mathematical space of the group of images accessed by Step 1710 may be determined based on pixel data of the images in the group of images. For example, the embedding in the mathematical space of at least the first image, the second image and the at least two more images accessed by Step 1710 may be determined based on pixel data of the first image, pixel data of the second image and pixel data of at least some of the at least two more images.

In some examples, the embedding in the mathematical space of the group of images accessed by Step 1710 may be determined based on pixel data of the images in the group of images and points in time corresponding to the group of images accessed by Step 1710. For example, the embedding in the mathematical space of at least the first image, the second image and the at least two more images accessed by Step 1710 may be determined based on pixel data of the first image, pixel data of the second image, pixel data of at least some of the at least two more images, the first point in time, the second point in time, and the points in time corresponding to at least some of the at least two more images. In some examples, a mathematical vector corresponding to an image may be concatenated with a mathematical value and/or a mathematical vector corresponding to a point in time, and the resulting mathematical vector for the relevant images and points in time (for example as described above) may be used to determine the embedding in the mathematical space of the group of images accessed by Step 1710, for example using principal component analysis (PCA), using Fisher's (linear discriminant analysis) LDA, using minor component analysis (MCA), using t-distributed stochastic neighbor embedding (t-SNE), and so forth. For example, the mathematical vector corresponding to an image may be generated by a mathematical vectorization of a matrix, where each entry in the matrix corresponds to a pixel in the image and comprise a value related to that pixel (such as gray level of the pixel, value of a color component of the pixel, value of an edge detector for that pixel, value of a convolution for that pixel, and so forth). In another example, the mathematical vector corresponding to an image may be generated by an object detector and comprise information about objects detected in the image by the object detector, such as number of detected objects, locations of detected objects, type of detected objects, properties of detected objects (such as size, color, etc.), and so forth. In yet another example, the mathematical vector corresponding to a point in time may comprise a single value corresponding to the number of time units passed since a particular time to the point in time, a vector with values describing the point in time (such as second, minute, hour, day, month, year, and so forth).

In some examples, in Step 1750 the determined embedding of the images in the mathematical space may be used to select additional images of the at least two more images accessed by Step 1710. For example, in Step 1750 the determined embedding in the mathematical space of at least the first image, the second image and the at least two more images may be used to select the third image of the at least two more images. In some examples, a centroid in the mathematical space of the embedding of the first image, the embedding of the second image, and in some examples embedding of other images, may be calculated. Further, the centroid may be used by Step 1750 to select additional images of the at least two more images accessed by Step 1710, for example by selecting the images closest to the centroid of the at least two more images accessed by Step 1710, by selecting the images farthest from the centroid, and so forth. In some examples, the images of at least two more images accessed by Step 1710 with the maximal minimal distance to the any one of the first image accessed by Step 1710 and the second image accessed by Step 1710.

In some embodiments, the group of images accessed by Step 1710 may be a group of frames of a video. For example, the first image may be a first frame of the video, the second image may be a second frame of the video, and the at least two more images may be at least two more frames of the video. Further, in some examples, in response to a first result of the analysis of Step 1740 (for example, in response to a first result of the comparison of the first annotation data and the second annotation data), a first frame rate may be selected, and in response to a second result of the analysis of Step 1740 (for example, in response to a second result of the comparison of the first annotation data and the second annotation data), a second frame rate may be selected, where the second frame rate may differ from the first frame rate. Further, in some examples, frames of at least part of the video may be sampled at the selected frame rate, for example as described below. Further, in some examples, the sampled frames may be presented to the user. For example, the obtained video of the selected frame rate may be played using a video player. In another example, individual frames of the sampled frames may be presented to the used, for example as described in relation to Step 1760. Further, in some examples, annotation data associated with the sampled frames may be received from the user. For example, annotation data related to the entire obtained video may be received (for example, with annotation data related to an action depicted in the obtained video, related to an event depicted in the obtained video, to motion depicted in the obtained video, and so forth). In another example, annotation data related to individual frames of the sampled frames may be received, for example as described in relation to Step 1770.

In some examples, frames of at least part of the video may be sampled at the selected frame rate. For example, the at least part of the video may be in a frame rate that is higher than the selected frame rate, and some of the frames of the at least part of the video may be dropped to obtain a video of the selected frame rate. In another example, the at least part of the video may be in a frame rate that is lower than the selected frame rate, intra-frames interpolation may be used to generate additional frames, and the generated additional frames may be added to the at least part of the video to obtain a video of the selected frame rate.

In some embodiments, in response to a first result of the analysis of Step 1740 (for example, in response to a first result of the comparison of the first annotation data and the second annotation data), a first image resolution may be selected, and in response to a second result of the analysis of Step 1740 (for example, in response to a second result of the comparison of the first annotation data and the second annotation data), a second image resolution may be selected, where the second image resolution may differ from the first image resolution. Further, in some examples, at least part of the selected third image may be presented in the selected resolution by Step 1760. Further, third annotation data associated with the third image may be received from the user as described above in relation to Step 1770, for example in response to the presentation of the at least part of the selected third image in the selected resolution. For example, the third image may be in an image resolution that is higher than the selected image resolution, and some of the pixels of the third image may be dropped to obtain an image of the selected image resolution. In another example, the third image may be in an image resolution that is lower than the selected image resolution, pixel interpolation may be used to generate additional pixels, and the generated additional pixels may be added to the third image to obtain an image of the selected image resolution.

In some embodiments, in response to a first result of the analysis of Step 1740 (for example, in response to a first result of the comparison of the first annotation data and the second annotation data), a first image augmentation may be selected, and in response to a second result of the analysis of Step 1740 (for example, in response to a second result of the comparison of the first annotation data and the second annotation data), a second image augmentation may be selected, where the second image augmentation may differ from the first image augmentation. Further, in some examples, the selected image augmentation may be applied to at least part of the third image to obtain an augmented image. Further, in some examples, at least part of the obtained augmented image may be presented to the user by Step 1760. Further, in some examples, third annotation data associated with the third image may be received from the user as described above in relation to Step 1770, for example in response to the presentation of the at least part of the obtained augmented image. Some examples of such image augmentations may include shifting the image, flipping the image, rotating the image, zooming, changing brightness, blurring the image, sharpening the image, applying a convolution to the image, cropping the image, and so forth.

In some embodiments, the first image and the second image accessed by Step 1710 and the first annotation data and the second annotation data received by Step 1730 may be used to train a machine learning algorithm and obtain an inference model, for example as described above with the first image and the second image with the corresponding annotations used as training examples in the training of the machine learning algorithm. Further, in some examples, the obtained inference model may be used to obtain at least one inferred result for each image of the at least two more images accessed by Step 1710, for example as described above. Further, in some examples, in Step 1750 the third image of the at least two more images may be selected based on a result of the comparison of the first annotation data and the second annotation data, the first point in time, the second point in time, the points in time corresponding to at least some of the at least two more images and the obtained inferred results associated with at least some of the at least two more images. For example, a machine learning model may be trained using training examples to select images of a plurality of alternative images based on comparison results and/or points in time and/or inferred results associated with the alternative images, and the trained machine learning model may be used to analyze the comparison of the first annotation data and the second annotation data by Step 1740 and/or and the points in time corresponding to the group of images accessed by Step 1710 and/or inferred results associated with at least some of the at least two more images and select the additional images of the at least two more images accessed by Step 1710. An example of such training example may comprise comparison results and/or points in time and/or inferred results, together with a desired selection of images of a plurality of alternative images. In another example, an artificial neural network may be configured to select images of a plurality of alternative images based on comparison results and/or points in time and/or inferred results associated with the alternative images, and the artificial neural network may be used to analyze the comparison of the first annotation data and the second annotation data by Step 1740 and/or and the points in time corresponding to the group of images accessed by Step 1710 and/or inferred results associated with at least some of the at least two more images and select the additional images of the at least two more images accessed by Step 1710.

In some embodiments, the first image and the second image accessed by Step 1710 and the first annotation data and the second annotation data received by Step 1730 may be used to train a machine learning algorithm and obtain an inference model, for example as described above. Further, in some examples, at least two augmented images may be generated for each image of the at least two more images accessed by Step 1710, for example as described above. Further, in some examples, the obtained inference model may be used to obtain a plurality of inferred results for each image of the at least two more images accessed by Step 1710, wherein the plurality of inferred results corresponding to any particular image of the at least two more images may comprise at least one inferred result for each augmented image of the generated at least two augmented images corresponding to the particular image. For example, each augmented image of the generated at least two augmented images corresponding to the particular image may be used as input to the obtained inference model to obtain an inferred result, for example as described above. Further, in some examples, the plurality of inferred results of each image of the at least two more images accessed by Step 1710 may be analyzed to obtain a stability assessment for each image of the at least two more images, for example as described below. Further, in some examples, in Step 1750 the stability assessments associated with at least some of the at least two more images accessed by Step 1710 may be used to select the third image of the at least two more images.

In some examples, the plurality of inferred results of each image of the at least two more images accessed by Step 1710 may be analyzed to obtain a stability assessment for each image of the at least two more images. For example, a plurality of inferred results may comprise two inferred results, the two inferred results may be compared to determine a measure of similarity (or a measure of dissimilarity) between the two inferred results, and the stability assessment may be based on the determined measure of similarity (or the determined measure of dissimilarity), for example by taking a function of the measure as the stability assessment. In another example, a statistical measure may be calculated for a plurality of inferred results (such as standard deviation, variance, and so forth), and the stability assessment may be based on the calculated statistical measure, for example by taking a function of the statistical measure as the stability assessment.

In some examples, in Step 1750 the stability assessments associated with at least some of the at least two more images accessed by Step 1710 may be used to select the third image of the at least two more images. For example, the image with the least stable plurality of inferred results of the at least two more images accessed by Step 1710 according to the stability assessments may be selected by Step 1750 as the third image. In another example, the stability according to the stability assessment of a plurality of inferred results corresponding to an image may be combined with additional information corresponding to the image (for example, information as described above) to obtain a combined score for the image, and Step 1750 may select the third image of the at least two more images based on the combined score (for example, selecting the image with the highest combined score, the image with the lowest combined score, the image with the combined score closest to a particular value, the image with the combined score closest to the mean of the combined scores, the image with the combined score closest to the median of the combined scores, and so forth).
